Abstract
The purpose of this study was to investigate the antifungal action of three single samples of South African honey (wasbessie, bluegum and fynbos) against Candida albicans. Various dilutions of honey were prepared in brain-heart infusion broth, ranging in concentration from 0 to 25% (w/w). This was inoculated with C. albicans, while a hypertonic sugar solution served as a control. All dilutions were incubated overnight and the optical density was measured in a spectrophotometer. The sugar control and the 3 honey samples stimulated the growth of C. albicans and was optimal between 2.5% and 5% . Increased honey concentrations resulted in reduced growth of C. albicans; wasbessie honey at a concentration of 25% demonstrated 29.4% inhibition on the growth of C. albicans, while the control, bluegum and fynbos honey produced only partial inhibition.

Key words: honey / antifungal action / antimicrobial action / oral micro flora / Candida albicans

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
